Berkeley Lab inventors receive a piece of the pie

By Jeffery Kahn

Technology transfer is not only of benefit to private industry and consumers, but to inventors. In December, Director Charles Shank handed out royalty checks to 13 Berkeley Lab inventors whose work has been licensed to private industry.

Technology Transfer Department Head Cheryl Fragiadakis said the dividends from technology transfer continue to grow.

"This year, the Laboratory is distributing more than double the dollars to almost twice as many inventors as last year," she said. "Licensing of Berkeley Lab technologies, whether as patents, copyrights or biological materials, continues to be a critical component in making sure scientific discoveries get into commercial use.

"I would like to offer my hearty congratulations to the inventors as well as to the divisions encouraging their work, and to the hard-working licensing staff that negotiated each of these one-of-a-kind business arrangements."

Gisella Clemons, a retired Life Sciences Division researcher who was the first inventor to receive royalties based on an invention licensed by the Lab, received her fourth annual royalty check. Clemons invented a method of producing an anti-serum that can be used to measure erythropoietin, a hormone produced by the kidneys that controls the production of red blood cells. The technology has been licensed to Diagnostics Systems Laboratories.

LSD researcher Eddy Rubin received a royalty check for the transgenic mice he has developed which express human apoB-100, a blood lipoprotein. The mice have been licensed to Eli Lilly and Company.

Judy Campisi and Goberdhan Dimri, also of LSD, are receiving royalties for the development of a biomarker for cellular senescence, a technique for identifying cells within living organisms that have reached old age. The technology has been licensed to the Geron Corp.

Energy and Environment Division researcher Greg Ward received a royalty check for his development of RADIANCE, lighting simulation software that has been licensed to the Genlyte Group, Inc.

E&E researcher Ted Chang and visiting scholars QuiQuan Yu and Yun Jin received royalty checks for their development of a sulfur dioxide catalytic reduction process. The technology has been licensed by The Ralph M. Parsons Co.

Earth Sciences Division researchers Chin-Fu Tsang and Frank Hale received royalty checks for their part in the development of a high-resolution instrument/software package for characterizing groundwater contamination. Their software has been licensed to COLOG.

Materials Sciences Division researchers Peter Schultz and Xiao-dong Xiang received royalties for their invention of a method for combinatorial synthesis. The process for making and testing many complex metallic materials in parallel has been licensed to Symyx Technologies.

Diane LaMacchia, formerly of the Public Information Department, received royalties for her production of two videos--"The Bevatron" and "The Search for Heavy Elements." These videos have been licensed to Pyramid Films and UC CMIL.

CAPTION: Among the 13 Lab employees who received a share of 1995 royalties for their patentable inventions are (left to right) Chin-Fu Tsang, QiQuan Yu, Ted Chang, Frank Hale, Xiao-Dong Xiang, Greg Ward, Goberdhan Dimri, and (far right) retiree Gisela Clemons. With them are E&E Division Director Elton Cairns, Deputy Director Pier Oddone, and Director Charles Shank.


Simple technology saves lives

By Diane LaMacchia

More than 400 children die every hour in the developing world from waterborne diseases such as cholera, typhoid, and dysentery. Scientists in the Energy and Environment Division have developed a simple water disinfection device that has the potential to stop these needless deaths.

"The technology itself is well understood," says physicist Ashok Gadgil, who is developing the device. "The potential impact is enormous."

In September, Gadgil and his colleagues shipped two of the devices to the Virgin Islands for disaster relief in the wake of devastating hurricanes that left much of St. Thomas and neighboring islands without safe drinking water.

The system uses ultraviolet (UV) light to kill germs, viruses, and molds. Compared to boiling water over a stove--a practice widely used in villages in China, for example--the UV disinfection system uses 20,000 times less energy. It is also much less expensive, capable of disinfecting water for only a penny a ton.

The method involves pumping contaminated water into a stainless steel disinfection chamber, where it flows beneath a UV lamp. The ultraviolet light inactivates the DNA of the bacteria and viruses exposed to it and renders them harmless.

The UV system is being field tested in India, where cholera has killed thousands in the past few years and where heavy monsoon rains add to water impurity by washing raw sewage into wells and surface water. Already, the fabrication shop in Bombay has given feedback resulting in a second generation of the device--one that is lighter weight and much more compact than the early prototype.

"Our goal," says Gadgil, "is something that is very low maintenance, low cost, and can be built in the developing world." The Lab's Technology Transfer Department has applied for a patent on the device--which has already been written up in Business Week--and plans to license it worldwide.

Ideally, the device will become part of a village's normal water source, incorporated into the daily water collection.

"The idea is that this device becomes part of the spout of a hand pump," says Gadgil. "The pump lifts water into the device, which means there is a single point for collecting disinfected water." The device can disinfect four gallons of water per minute; by comparison, water flows from a typical American bathtub at three gallons per minute.

Electricity to power the lamp is not a problem, since 80 per cent of Indian villages have electricity. In one field-test site that does not have electricity, the villagers are using a car battery that they exchange for a charged one in the next town; their UV disinfection unit has been running steadily for almost a year.

The plan for using the device includes a technician who installs the device, then returns to the village or city every six months to provide regular maintenance, replacing the lamp every other visit. Hand pumps in India are already serviced regularly by such a network of technicians.

The UV system will benefit women who now spend hours and even days at a time gathering cooking fuel, because they will not have the added burden of getting enough fuel to boil water. In addition, there will be less pressure on the forests, already largely depleted in India.

Alternatives to the UV disinfection system have drawbacks. If the water is not treated at all, people get sick. Boiling water is energy intensive. Some people add chlorine to water, which affects its taste and requires a trained person at the site to make sure that levels do not get too high. A regular supply of chlorine is required; the spread of cholera has been traced to interruptions in the supply of chlorine. Chlorine treatment or appropriate filtering is still needed in places where giardia are present; UV light does not kill giardia.

Gadgil and his colleagues, including mechanical engineer Derek Yegian, engineering graduate student Todd Reynolds, visiting physicist Edas Kazakevicius of Lithuania, and post doc Marc Fischer, have worked closely with health and community leaders in India. A number of other researchers have worked on the project as well.

CAPTION: Researcher Ashok Gadgil and colleagues have developed a simple, but life-saving, water disinfection system.


Paper use study reveals simple ways to cut copying costs

By Brennan Kreller

Copy machine users throughout the Lab were unsuspecting targets in a recent paper use study conducted by the Energy Analysis Program. The study, funded by the EH&S Waste Minimization Program, focused on determining the frequency with which employees double-side their copies, and on increasing two-sided copying at the Lab.

E&E's Bruce Nordman monitored the users of the Canon 6650 II because it is the most common copier at the Lab and has a very reliable and efficient duplexing feature. He found that employees already double-side their copies much more often than the national average.

Nordman enlisted the help of high school summer student Ericka Mosley to find out if a reminder and posting of guidelines would motivate employees to double-side their copies even more often. First the two labeled the Canon 6650 copiers with simple reminders to use the duplexing feature. Later, they replaced the labels with a one-page "How to Copy More Efficiently" guide.

The first labeling, the simple reminder, resulted in an increase of 8 percent in the duplexing rate to 40 percent, more than double the national rate for that class of machine.

When the more detailed duplexing guide was posted, the rate of double-siding copies remained at about 40 percent. Nordman said, however, that it might still help to maintain the higher duplexing rate.

Even the small increase in duplexing is significant, Nordman says, because the paper saved amounts to 1.7 tons and $1,700 in paper purchase costs just for the 6650 models.

Nordman says there are even more savings involved when you consider other costs of using paper, such as transporting and storing it, mailing it, and disposal or recycling. Each step adds costs, estimated from the study at 10 times the purchase price of the paper. For the Laboratory, which spends about $200,000 a year on office paper, this amounts to more than $2 million annually.

"The completely paperless office may be a silly idea, but we can cut down significantly if we invest resources in doing so," Nordman says. He recommends using less paper in general, and double-sided copying whenever possible.

For more information on the paper use reduction study, or for copies of the duplexing guides and reminders to post by your copy machine, contact Nordman at X7089 or [email protected].

CAPTION: E&E's Bruce Nordman monitored Lab copying practices to find ways to decrease paper use.


In Memoriam -- Mary Wildensten

Laboratory retiree Mary V. Wildensten died on Dec. 1 in Castro Valley. She was 70.

Wildensten worked at the Lab from 1971 until 1979 as a technical writer and editor in the Technical Information Department. As managing editor of Research/Accelerators, she received a national award from the Society for Technical Communications in 1979.

She freelanced for a short time as a technical editor and writer before becoming head of technical communications for Cyclotron Corporation of Berkeley in the early 1980s. She later accepted a similar position at Imatron of South San Francisco.

Upon retirement, Wildensten became a contributing writer and editor for the Sierra Club's monthly, The Yodeler. She was a past board member of Bay area Community Services, where remembrances may be sent in her name (Attn: Susan Garbuio, Bay Area Community Services, 7901 Oakport St., Suite 2400, Oakland, CA 94621).

Wildensten is survived by one brother, David Vaughan of Bozeman, Mont.; sons Craig and Roger; and two granddaughters.

Advanced Light Source hits jackpot with LOTO center

The Advanced Light Source has significantly improved its operations safety with an efficient and simplified system for Lockout /Tagout (LOTO).

LOTO is the OSHA and DOE-mandated procedure for de-energizing and securing energy systems to allow servicing, maintenance or modifications. The ALS is one of the Laboratory's most concentrated LOTO use areas; it is estimated that the ALS performs more than 1,100 LOTO operations each year, resulting in a considerable allocation of resources.

Recognizing that the existing system was inefficient, ALS Electrical Engineering group leader Henry Lancaster asked Electronics Coordination supervisor Art Ritchie to create a Process Improvement Team. Ritchie appointed Ken Baptiste, Jim Gregor, Rita Jones, and Bob Mueller from the ALS, and Keith Gershon from EH&S to the PIT. After only two meetings, the team had completely restructured ALS LOTO into a centralized system that is easier to use and 50 percent more efficient than the old system.

"The first thing we found was that the physical layout of the ALS was responsible for a lot of wasted time," Ritchie says. "Technicians spent an inordinate amount of time traversing the storage ring because the work site is usually nowhere near the LOTO equipment and logbooks."

Ritchie immediately started work on a custom LOTO center located inside the ring, where most of the LOTOs occur. All locks, tags, logbooks, and accessories are now found in one convenient location near the work sites.

"This is a substantial safety improvement," says Gershon. "Whenever the individual worker perceives that his time is being wasted, he is less likely to implement safety procedures. A common cause of workplace injuries is time pressure. The ALS has always been very serious about LOTO, and with this new system the ALS shows that safety and efficiency can be compatible."

Anyone who would like to duplicate the LOTO center may obtain the drawings from Ritchie at X4785.

CAPTION: A Process Improvement Team consisting of (top row) Keith Gershon, Ken Baptiste, Bob Mueller and (bottom row) Jim Gregor, Rita Jones, and Art Ritchie developed a new and improved lockout/tag-out system for the Advanced Light Source.
